We argue that the validity of the WKB approach for calculating nonequilibri
um properties of a nonlinear stochastic system requires an additional crite
rion involving the time interval, compared with the standard WKB criterion
considered by Mannella [R. Mannella, Phys. Rev. E 58,2479 (1999)]. In order
to clarify the situation, we compare the WKB solution with the direct nume
rical solution of the Fokker-Plank equation.
